Green tea extract helps prevent HIV
A green tea compound is found to inhibit sexual transmission of HIV virus when used as an ingredient in vaginal creams. German researchers discovered that the green tea polyphenol, called epigallocatechin-3-gallate (EGCG), is capable of neutralizing a protein in sperm which serves as a vector for viral transmission during sex. Scientists believe that EGCG could provide a simple and affordable prevention method for poor and developing nations, and would also enable women to ensure proper protection during sexual intercourse.
